Spokesman Jerry Bates said deputies responded to a call at 10:17 p.m. of a suicidal man in his 40s armed with a knife in the 2000 block of 78th Street Court East. Bates said the man was possibly high on drugs and upset about a breakup.

A confrontation led to one of the deputies firing his weapon and killing the man, Bates said.

The deputies were not injured, he added.
